The new chiral diphosphine ligand [(5,6), (5%,6%)-bis(1,2-ethylenedioxy)biphenyl-2,2%-diyl]bis(diphenylphosphine) (Bisben-zodioxanPhos) has been successfully prepared and used in ruthenium-catalyzed asymmetric hydrogenation of 2-(6%-methoxy-2%naphthyl)propenoic acid and b-keto esters with high enant
Optically active diphosphine (S,S)-2,2"-bis[(diethylphosphino)methyl]-1,1"-biferrocene (abbreviated to (S,S)-EtTRAP-H) was synthesized from ferrocenyloxazoline derived from L-valinol in 47% overall yield. The new chiral ligand, (S,S)-EtTRAP-H, which coordinates to a rhodium atom in a trans-ehelating
